Product Features:
1. The CNC angle iron punching machine is equipped with either two or three punching units, each capable of handling three different punch sizes. These punching units are precisely controlled by numerical control (NC), ensuring accurate and adjustable punching positions. The machine can produce both round and oval holes. With its high-speed feeding and punching capabilities, it significantly enhances production efficiency. For 50×50×4mm angle steel, the machine achieves a production capacity of 9-10 tons per eight-hour shift.
2. The marking unit of the CNC angle punching machine is housed within a sturdy and durable enclosure. The marking system consists of four cassette sets, selectable via programming, offering flexibility in adjusting the marking position. Furthermore, the machine uses a disc marking method with 10 rows, automatically selecting characters without manual input, thereby greatly improving marking efficiency.
3. The CNC angle bar cutting machine is equipped with a single-blade shearing unit, known for its superior cutting force. Each cut is performed with zero material waste, resulting in a clean, smooth cutting surface. The blade housing features an open-door design, allowing for quick and safe blade changes.
4. The horizontal material table efficiently transfers the angle bar to the rotating material rack, which is powered by a motor and reducer. This system ensures the secure positioning of the angle bar onto the feeding conveyor for further processing.
5. The workpiece is securely held and fed by a CNC feeding carriage, guaranteeing precise alignment and positioning accuracy. The feeding carriage is driven by a servo motor, with position feedback provided by a photoelectric encoder, operating within a closed-loop control system.
6. The CNC angle steel metal punching and marking machine is powered by a hydraulic system that drives the punching, marking, and shearing operations. It is equipped with a high-speed hydraulic station featuring an accumulator, and the hydraulic lines utilize ferrule-type connections to ensure leak-free operation while simplifying maintenance and replacement. The primary hydraulic valve blocks are sourced from the renowned Atos brand, guaranteeing a reliable and high-performance hydraulic system.
7. The hydraulic station’s cooling system offers various options, including water cooling, air cooling, or oil chilling. This flexibility allows customers to choose the most appropriate cooling method based on their specific operational needs.
8. The control system comprises an upper computer, PLC, servo motor, external detection switches, and other integrated components. The operator simply inputs the processing specifications, and the system automatically generates the corresponding processing program. It is fully compatible with file formats such as DXF, NC, and others generated by CAD software. The upper computer’s human-machine interface is user-friendly, featuring an intuitive display and simplified operation. It offers functionalities such as graphical workpiece visualization, extensive data storage, position tracking, and fault alarm notifications.
These samples, which reflect standard specifications and typical processing conditions in the angle steel tower industry, provide users with an opportunity to directly evaluate the equipment’s processing quality, accuracy, and craftsmanship. They serve as a concrete reference for assessing the equipment's performance and its alignment with specific production needs, thus facilitating informed, data-driven decision-making for potential applications.
In the construction of ultra-high voltage (UHV) transmission lines, where towers are subjected to extreme weather conditions and substantial loads, this equipment is essential for processing the angle steel components that form the core structural framework of the towers. It effectively carries out drilling and stamping operations on the angle steel used for tower bodies, cross-arms, and other critical structural elements, ensuring precise dimensions and strong connections that maintain the overall stability and integrity of the towers.
